Thank you very much, Mr. Chair.
First, let me thank the witnesses for coming and sharing their expertise with us. It's very much appreciated.
Dr. Lyon, I noted that you started off your opening statement by talking about the definition of surveillance. That was in stark contrast, quite frankly, to what Minister Duclos shared with this committee, but your comments seem to be consistent with those of some of the other experts we've heard from. Can you comment further on your feelings as to what Minister Duclos said before this committee in suggesting that surveillance was not involved?
